- 1,635,608 July, 1927' M. BRETO$ Y CLAVERIA AWNING Filed April 5. 1924 INVENTOR. 7 gram y 6/4/1272 BY %t4 r ATTORNEYS The hoisting cable 17, wound on the reel 14:, is passed up between the rollers 6, over guide pulleys 18' and 19, mounted in pulley casings 18 and 19 on the ends of a collapsible shaft 20 supported by brackets 21, and the pulley casings also have an oscillating movement due to a slot, and stop engagement 20.

Attention is called to the fact that'the shaft 20, being hollow, the cable 17 can be guided through it from the pulley 18' to the pulley 19 and then downwardly, under apulley 22 in a pulley casing 22vat the upper part of the door, then in and over a pulley 23 in the pulley casing 23 held under the top of the door. around a guide pulley 24 which is mounted in the end of a bracket 25 fastened to the lower part of the awning and then over a pulley 23' in the pulley casing 23, under a pulley 22 in the pulley casing 22", to be fastened at the lower end of the pulley casing 19. V

Besides the arrangement explained, a shock absorber is provided for the awning, consisting of a bracket 27, and a rod 28 around which is coiled a spring 29, and which operates a stop 26 inside of which is lodged the spring 29.

To operate the folding or the extending of the awning it is only necessary to pull downward or push upward on the cable 17 to effect the folding of the awning as is shown in dotted lines in Fig. 1, or the extending of the same as is shown in full line in the same figure, it being understood that the reel 14,

fixed relatively to the drum 11, due to the engagement of the pawl 15, together with the hoisting cable 17, will be wound in one direction or the other due to the tension of spring 12, when it is moved.

The shock of operation. of the awning will. be taken up by the flexible stop 26.

When it is desired to vary the tension of the spring 12, the screws which hold the plate 9 to the casing 5 will be'removed, and

the standard of the drum will be pulled outwardly, the notches 8 being held in engagement with the pins 5 of the casing 5 and ill) the arm 13, the free end of which presents a recess for supporting the same, will rest on pin 5, and the bracket 7 will hang outwardly as shown in Figure 7 to permit handling as desired.

Being in the position shown, if it be desired to vary the tension of the spring,-the pawl 15 is disengaged from its adjustment notches, and the reel 14 will remain loosely mounted around the drum 11, and will be turned (see Figure 3) until one of the pins 11" engages stop arm 16, so that upon moving the drum 11 forward, with a suitable tool, which will beengagedby pins ll the tension of the spring '12 can be varied by the rotation of the drum 11, in the proper direction. This being done, the reel 14 is turned so that the notch 14:" of the same will register with the notch 11 of the drum, when the pawl 15 will become engaged, the reel 14 therein being again held fixed to the drum 11, and the drum standard can again be housed in casing 5.

Having described my invention and one manner in which same can be performed, what I wish to protect is the following:

1. An operating means for awnings and the like, comprising, a standard, a shaft fixed in the standard, a drum rotatably mounted on the shaft, a reel rotatably carried by the drum, matching notches on the drum and reel, a detent receivable in the notches to fix the reel to the drum, and a spiral spring housed in the drum, one end of the spring being fixed to the shaft and the other end to the drum.

2. An operating means for awnings and the like, comprising, astandard, a shaft fixed in the standard, a drum rotatably mounted 011 the shaft, a reel rotatably carried by the drum, matching notches on the drum and reel. a detent receivable in the notches to fix the reel to the drum, a spiral spring housed in the drum, one end of the spring being fixed to the shaft and the other end to the drum, pins projectingv from one side of the drum for rotating the drum, and a stop arm pivoted to the standard and cooperating with the pins. g

3. An operating means for awnings and the like, comprising, a standard, a shaftfixed in the standard, a drum rotatably mounted on the shaft, a reel rotatably carriedby the drum, matching notches on the drum and reel, a detent receivable in the notches tofix the reel to the drum, a spiral spring housed in the drum, one end of the spring being fixed to the shaft and the other end toth'e drum, the standard including a front plate and spaced projecting arms between which arms the drum is mounted, the upper edges of the arms being notched, a holding arm pivoted to the front plate, an open ended casing to receive the standard and parts carried thereby, and pins on the casing projecting inwardly thereof to engagingly cooperate with the notched arms and holdmg arm when the standard and its parts are partly withdrawn from the casing. I

4. An operating means for awnings and the like, comprising, a-standarcha shaft fixed in the standard, a drum rota-tably mounted on the shaft, a reel rotatably carried by the drum, matching notches on the drum and reel, a detent receivable in the notches to fix the reel to the drum, a spiral'spring housed in the drum, one end of the spring being fixed to the shaft and the other end to the drum,pins projecting from one side of the drum for rotating the drum, a stop arm pivoted to the standard and cooperating with the pins, the standard including afront plate and spaced projecting arms between lOU which arms the drum is mounted, the upper edges of the arms being notched, a holding arm pivoted to the front plate, an open ended casing to receive the standard and parts carried thereby, and pins on the casing projecting inwardly thereof to engagingly moperate with the notched arms and holding arm when the standard and-its parts are partly withdrawn from the casing.

5. An operating means for awnings and the like, comprising, a standard, a shaft fixed in the standard, a drum rotatably mounted on the shaft, a reel rotatably carried by the drum, niatcl'iinp; notches on the drum and reel, a detent receivable in the notches to fix the reel to the drum, a spiral spring housed in the drum, one end of the spring being fixed to the shaft and the other end to the drum, the standard including a front plate and spaced projecting arms between which arms the drum is mounted, the upper edges of the arms being notched, a holding arm pivoted to the front: plate, n open ended casing to receive the standard and parts carriedthereby, pins on the casing PIOjQUt-lllg inwardly thereof to cooperate with the notched arms and holding arm, two of the pins being positioned at the level of the top edge of the arms when the standard is inserted into the casing, and a third of the pins being positioned above the level of said two pins, the notched arms, and the holding arm receiving the said three pins to hold the standard and its parts in a posi tion partly withdrawn from the casing for facilitating adjustment of the spiral spring tension.

6. An operating means for awnings and the like, comprising, a standard, a shaft fixed in the standard, a drum rotatably mounted on the shaft, a reel rotatably carried by the drum, matching notches on the drum and reel, a detent receivable in the notches to fix the reel to the drum, a spiral spring housed in the drum, one end. of the spring being fixed to the shaft and the other end to the drum, pins projecting from one side or the drum, a pawl pivoted to the standard and cooperating with the pins, the standard including a front plate and spaced projecting arms between which arms the drum is mounted, the upper edges of the arms being notched, a holding arm pivoted to the front plate, an open ended casing to receive the standard and parts carried thereby, pins a position partly withdrawn from the casing for facilitating adjustment of the spiral spring tension.

In testimony whereof I have signed my nameto this specification.
